Sec. 463.2  General definitions.



    In addition to the definitions set forth in 40 CFR part 401, the 

following definitions apply to this part:



[[Page 548]]



    (a) ``Plastics molding and forming'' is a manufacturing process in 

which plastic materials are blended, molded, formed, or otherwise 

processed into intermediate or final products.

    (b) ``Process water'' is any raw, service, recycled, or reused water 

that contacts the plastic product or contacts shaping equipment surfaces 

such as molds and mandrels that are, or have been, in contact with the 

plastic product.

    (c) ``Contact cooling and heating water'' is process water that 

contacts the raw materials or plastic product for the purpose of heat 

transfer during the plastics molding and forming process.

    (d) ``Cleaning water'' is process water used to clean the surface of 

an intermediate or final plastic product or to clean the surfaces of 

equipment used in plastics molding and forming that contact an 

intermediate or final plastic product. It includes water used in both 

the detergent wash and rinse cycles of a cleaning process.

    (e) ``Finishing'' water is processed water used to remove waste 

plastic material generated during a finishing process or to lubricate a 

plastic product during a finishing process. It includes water used to 

machine or to assemble intermediate or final plastic products.

    (f) ``Plastic material'' is a synthetic organic polymer (i.e., a 

thermoset polymer, a thermoplastic polymer, or a combination of a 

natural polymer and a thermoset or thermoplastic polymer) that is solid 

in its final form and that was shaped by flow. The material can be 

either a homogeneous polymer or a polymer combined with fillers, 

plasticizers, pigments, stabilizers, or other additives.

    (g) ``Crude intermediate plastic material'' is plastic material 

formulated in an on-site polymerization process.

    (h) ``Mass of pollutant that can be discharged'' is the pollutant 

mass calculated by multiplying the pollutant concentration times the 

average process water usage flow rate.
